ZDI-23-1492: Linux Kernel XFRM Out-Of-Bounds Read Information Disclosure Vulnerability
First published: Fri Sep 29 2023(Updated: )
This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of state filters. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute arbitrary code in the context of the kernel.
